Hi! I just picked up my first pair of Astro headsets. I got the A40 TR Headset + MixAmp™ Pro TR for the Xbox One X. My purpose for using them is primarily COD - Blackout for hearing footsteps/environment around me better. My friends were telling me about the Fusion Ultimate 5.15 A50 FPS Extreme... But I was also reading about the Fusion Ultimate FPS Extreme 5.91. I don't exactly know how to set my headset to this or what these mean - But I know I want the best sound config for my gaming experience. What is the difference between these two? Which one do you recommend so I can hear footsteps etc better/more distinctly? As a reference I was referring to: 1. http://forums.astrogaming.com/index...vYiw334iZ-hXTQXJ08qRlc_zoeBUHYjK6--WqHiQgajMc 2. http://forums.astrogaming.com/index...WayV58hgiqwoa2r-KNkKVR45D2CFkfU5U-2qhcE50C1WU Thanks!!
